Still, if you are getting less than the recommended seven to eight hours of sleep a night you may need more than a cup of coffee to make up for it. Sleeping an extra hour or two a night can improve your health, productivity and mood.

Better mood
Lack of sleep causes your body to produce more stress hormones and effects your emotional regulation. If you get enough sleep you’ll get along better with your family, co-workers and friends.

Memory
Having trouble finding your keys? Studies have shown sleep is when our brain consolidates memories from the day. If you get enough sleep your short and long term memory will improve.

Sleep is healthy
Lack of sleep has been linked to hypertension, increased stress hormone levels, cardiac arrhythmias, and increased inflammation. Getting enough sleep is an important factor in preventing heart disease and staying healthy.

Smarts
According to a recent report every hour of sleep lost below the recommended 7 to 8 hours represents a loss of approximately one point on a person’s IQ.

Sleep boosts your immune system
Sleep deprivation can affect your immune system, making it weaker, and leaving you more prone to illness and viruses. Getting enough sleep will reduce your chances of getting a common cold and can even help your flu shot work better.

Safety
A significant lack of sleep can have similar effects as alcohol, and cause you to have delayed reactions to different stimuli. Being well-rested is important when driving, exercising and performing other activities that require physical coordination.

Sleep can improve your mental well-being
Sleep impacts many of the chemicals in your body. Sleep’s role in regulating hormones and chemicals in your body makes it an essential component of your mental health.

Clearer-thinking
Studies have shown that lack of sleep impairs your cognition, attention and problem solving. Lack of sleep can even increase your chances of making odd mistakes like leaving your keys in the fridge.

Energy
Not getting enough sleep can leave you feeling lethargic and drowsy. Sleep is essential in maintaining energy levels and allowing you to be at your best all day.
